Defined in header <atomic>
template< class T > void atomic_store( std::atomic<T>* obj, T desr );	(1)	(since C++11)

1-2) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr)

3-4) Atomically replaces the value pointed to by obj with the value of desr as if by obj->store(desr, order)

[edit] Parameters

obj	-	pointer to the atomic object to modify
desr	-	the value to store in the atomic object
order	-	the memory sycnhronization ordering for this operation: only std::memory_order_relaxed, std::memory_order_release and std::memory_order_seq_cst are permitted.

[edit] Return value

none.
